Abstract:

BACKGROUND: Aesthetic repair on tetracycline stained teeth is mostly confined to the clinical observation, while the experimental study is relatively few.
OBJECTIVE: To study the color changes of Cerinate porcelain veneer repaired tetracycline stained teeth: mild (yellow), moderate (dark gray), severe (yellow-gray), very severe (taupe).
METHODS: Simulated tetracycline stained teeth were divided according to staining degree into four groups: mild, moderate, severe, and very severe groups; each group had ten specimens which were repaired with Cerinate porcelain veneer, bonded with Panavia F opaque resin adhesive. The L*, a*, b* values of specimens before and after bonding was measured by electronic color measurement instrument.
RESULTS AND CONCLUSION: Before and after bonding, the values of L*, a*, b* were significantly different (P < 0.05). Mild tetracycline stained teeth bonded using resin adhesive without opaque bonding have a better effect than moderate and severe tetracycline stained teeth bonded with opaque resin adhesive; while, it is best to use other restorations to repair very severe tetracycline stained teeth.
